Yes, but it is a departure from teaching, so is the word “departure” used to translate the same Greek word? If so, then we are witnesses of a great departure from the teaching of Truth. In fact, today it is taught that there is no absolute truth bringing with it a hatred of The Truth and His followers of every nation, tribe, tongue, and people.
That is in fact an excellent notion. It can be valued as a teacher for our epoch. As used in 2Thess2:3 the meaning could be as you infer. However, we have the passages following that verse which point to the restrainer being removed. The Restrainer is the Holy Spirit Who indwells the Bride of Christ, The Church.
